The description of a man who is suspected of wounding four people with a knife at a gym in Duisburg, Germany, has been released. Investigators are looking into a possible motive.

Investigators were still looking into a possible motive, however it appeared that it was not an indiscriminate attack, said Herbert Reul, the state interior minister of North Rhine-Westphalia, where Duisburg is located. He did not elaborate.

"I hope that the victims will recover quickly and that everyone who was on the scene and saw this terrible act will recover," Reul added.
